Q. My turbo has a
pipe and/or aftermarket filter, and in the higher gears under full
acceleration it "cuts out" for a second or so, then the power
comes back on. What's wrong with it?
A. Nothing is wrong.
The pipe and filter allow the turbo and engine to breathe more
freely and require more fuel. The stock ECU isn't programmed for
this, so cuts the injection for a moment until settings are back
to normal. You can prevent this happening by enabling "race mode".

Q. Where can I
get a manual for this bike?
A. There are two
manuals, the base manual for the GPz750 which covers the basic
bike, and the turbo supplement, which covers everything specific
to the turbo version. You can hunt down copies on ebay or download
them here:
Base Manual (44mb pdf)
Supplement (26mb pdf)
Q. The DFI
warning light on the tank console is flashing. What should I do?
A. The DFI warning
light is to draw your attention to the ECU in the tailpiece, which
has an LED that flashes a code, like morse code, if there is a
problem with a sensor, or the ECU itself. The table below shows
what action is required.

Q. I can't seem to get any
gear other than 1st or neutral, is there something wrong with the
gearbox? A. No, all
Kawasakis have a "positive neutral finder" to help you select
neutral from first gear when stationary. Unless the bike is
moving, you won't be able to select the other gears. When you are
moving all five gears will be available.
Q. I can get "high octane" fuel
locally, will it make my bike faster?
A. If the bike is running stock
boost it won't make it any faster, and could possibly make it
slower. High octane fuels generally contain less heat energy than
regular unleaded. With increased boost high octane fuel will help
resist detonation, which is uncontrolled burning of the fuel.
Running increased boost without detonation is the key to making
more power. Q. How much
boost can I run on super unleaded fuel?
A. This will depend greatly on how
accurately the engine is fuelled, how healthy the engine is and
other factors. Owners should use a wideband lambda sensor, or a
dyno equipped with one, to monitor progress carefully.
